This document discusses the design of different types of staircases, including straight flight stairs, quarter-turn stairs, and half-turn stairs. It defines technical terms related to stair design like tread, riser, rise, and landing. It also describes the loading and design considerations for different types of stair support, like simply supported stairs, cantilever stairs, and longitudinally supported stairs. Examples are provided to demonstrate how to calculate loads, design for shear and flexure, and determine reinforcement requirements for staircase design.

The document describes the design of a waist-slab type staircase. It includes:
1) Calculating the effective span of the going and landing slab as 5100 mm and selecting a 250 mm depth.
2) Determining factored loads on various elements, with the maximum being 22.9 kN/m^2 on the going.
3) Analyzing the slab for bending moment and shear force, finding a maximum moment of 102.08 kNm at 2.51 m from the left support.
4) Checking that the selected depths of 250 mm and 200 mm are adequate based on the bending moment.
The document is a bridge design calculation sheet that includes:
1) Calculations for bending moment, section properties, reinforcement sizes and spacing, shear resistance, and crack width control for a bridge section.
2) The calculations determine that the main reinforcement area of 1631.63 mm^2 is sufficient, secondary reinforcement of 392.86 mm^2 is also sufficient, and the calculated crack width of 0.2300 mm is less than the design limit of 0.25mm.
3) All design checks are shown to satisfy code requirements indicating the bridge design is adequate based on the given loads and material properties.
This document provides an introduction to different methods of connecting floors at different levels, including ladders, steps/stairs, escalators, lifts, ramps, and trolley-rope-ways. It then defines various technical terms related to stair design, such as tread, riser, rise, nosing, flight, landing, slope, strings, soffit, balusters, and headroom. Finally, it discusses principles for planning and designing stairs, including recommended widths, lengths, pitches, and step proportions.
Reinforced concrete is well-suited for constructing stairs due to its fire resistance, durability, strength, and pleasing appearance. R.C.C. stairs can be designed in various forms including straight flights, inclined slabs with half landings, string beams, cranked slabs, cantilevers, and spirals. The type of stair adopted depends on the space and loading conditions. Common stair arrangements include single straight flights, inclined slabs spanning longitudinally, string beams with horizontal slab spanning, cranked slabs inducing bending and torsion stresses, cantilever stairs with central supporting walls, and spiral or helical stairs used in prestige buildings.
This document provides information about different types of stairs. It defines key stair components like steps, treads, and risers. It then describes 8 common types of stairs including straight stairs, dog-legged stairs, quarter turn stairs, and spiral stairs. Each type is defined and the suitable applications are outlined. The document aims to inform about the different shapes, materials, and styles of stairs that can be used in buildings.
The document discusses the design of staircases. It begins by defining key components of staircases like treads, risers, stringers, etc. It then describes different types of staircases such as straight, doglegged, and spiral. The document outlines considerations for designing staircases like dimensions, loads, and structural behavior. It provides steps for geometric design, load calculations, structural analysis, reinforcement design, and detailing of staircases. Numerical examples are also included to illustrate the design process.
The document discusses different types of staircases and important considerations for staircase design and construction. It covers the evolution of staircases and why they are needed, as well as principles for planning and designing stairs, including width, pitch, handrails, and recommended tread and rise proportions. The document also examines different stair materials, lighting requirements, and styles of stairs including modern, classic, curved, and traditional designs.
